Integrate @bgotink/playwright-coverage for E2E test coverage tracking:
Install @bgotink/playwright-coverage package
Update playwright.config.js with coverage reporter
Update test file imports to use coverage-enabled test function
Add e2e-tests.yml coverage artifact upload and merge job

Coverage outputs: HTML, LCOV, JSON to coverage/e2e/
CI uploads merged coverage to Codecov with 'e2e' flag
Enables unified coverage view across unit and E2E tests
Add comprehensive E2E testing infrastructure including:
docker-compose.playwright.yml for test environment orchestration
TestDataManager utility for per-test namespace isolation
Wait helpers for flaky test prevention
Role-based auth fixtures for admin/user/guest testing
GitHub Actions e2e-tests.yml with 4-shard parallelization
Health check utility for service readiness validation
